Previously, we’ve looked at the most recent time I’ve seen each of the 30 major league baseball teams play. Three weeks into the 2026 season, I thought it would be worth going into the wayback machine and see when the first time was that I saw each team live and in person, to the best of my knowledge. My records only go back to 1984, so anything before that is as yet unidentified.
Breaking it down by decade, we have twelve teams I saw originally during the 80s, eleven in the 90s, and the remaining seven came in the 2000s. For franchises that have moved, I have lumped them all together.
